However you should update use jdk1.3.1to run jbuilder.to do that change the folowing file$JBUILDER_HOME/bin/jdk.conf

mine looks like this

#===============# Set the path for the JDKjavapath /home/pmn/java/jdk1.3.1/bin/java# Add the tools.jaraddpath /home/pmn/java/jdk1.3.1/lib/tools.jarvmparam -Xverify:none# +-----------------------------------------------------+# | |# | Uncomment the following line if you are having |# | problems with your default file encoding. This |# | problem is evident in some locales |# | |# +-----------------------------------------------------+vmparam -Dfile.encoding=ISO8859_1

with the jdk1.3.1 the problemof huge windows is solved in KDEbut code insigth does not work :-))
